Answer:
78 meters
Step-by-step explanation:
the big one is 9 x 10 =90 meters
The smaller one is 3 x 4 =12 meters
the remaining area is 90-12=78 meters
Consecutive even integers..x, x + 2, x + 4
x + (x + 2) + (x + 4) = 6216
3x + 6 = 6216
3x = 6216 - 6
3x = 6210
x = 6210/3
x = 2070
x + 2 = 2070 + 2 = 2072
x + 4 = 2070 + 4 = 2074 <===house 3
It is a 5% discount 400 x .05 = 20
400 - 20 = 380
